How did Egyptians attempt to measure time?

The ancient Egyptians were one of the first cultures to widely divide days into generally agreed-upon equal parts, using early timekeeping devices such as sundials, shadow clocks, and merkhets (plumb-lines used by early astronomers). Obelisks are used by reading the shadow that it makes.

To complete the year, five intercalary days were added at its end, so that the 12 months were equal to 360 days plus five extra days.

Why was time created?

To help us better understand and navigate our lives, however, people long ago assigned standards of measurement that would help to get a grasp of the passage of time. The natural rotation of the Earth on its axis and the revolution of the Earth around the Sun give us our two most basic measurements of time.

Who invented telling time?

The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today’s clocks measure.
